Declarative phrase appearing at the end of a statement which effectively negates the meaning of the previously stated text. Essentially, the presence of this statement instructs the reader that what has been stated up to this point is a fallacy in that no one would make that statement under any circumstances, at any time (in the past, present or future) in any corner of the known universe.
